“…However, due to the linear characteristic of FEM, it is inapplicable on nonlinear deformable object. Even though it could simulate nonlinear object accurately, it only works on a small body distinct (Srinivasan et al, 2006;Tendick et al, 2000;Webster et al, 2002). This is because FEM consists of linear model; additional linearization is embedded in the procedure to linearize the nonlinearity, thus increase the time complexity.…”
